Mercedes-Benz CLE DPF Replacement Parts

The engine code is the most important thing to get right when sourcing a used DPF for your CLE — different engines use different DPF assemblies even within the same model range, so a unit from the wrong engine will not fit correctly. You'll find the engine code on your V5C or can ask a dealer to read it from the VIN. Always quote your exact engine code to the breaker when requesting a quote, as well as your registration plate so they can cross-reference.

No — DPF units are engineered to the emissions standard of the vehicle they were built for, and a Euro 5 DPF will not satisfy the requirements of a Euro 6 system, which could cause the car to fail its MOT. The CLE is a model introduced from 2023 onwards, so all UK examples fall within Euro 6 (and later Euro 6d) territory, meaning this cross-era concern is less likely to arise within the CLE range itself. That said, whether a specific part from one CLE registration year interchanges with another should be confirmed with the breaker against your exact registration, as software and emissions sub-variants can differ.

Trim level does not affect DPF fitment on the CLE — the DPF is determined by the engine and emissions specification, not whether the car is a standard, AMG Line, or other trim variant. You can therefore source a DPF from any CLE with the same engine code and emissions spec regardless of trim, though minor cosmetic differences in surrounding components are possible. Confirm the engine code match with the breaker against your registration to be sure.

Even where the CLE shares engine codes with the C-Class (W206) or E-Class (W213/W214), the DPF assembly and surrounding pipework may differ due to different underbody packaging and exhaust routing. This is strong confirm-with-the-breaker territory — quote your exact registration and engine code to any breaker and ask them to verify the part number matches before you agree to buy. Do not assume a DPF will cross over between models even if the engines appear identical on paper.

Ask the breaker about the mileage of the donor vehicle and whether any DPF warning lights were present before the car was dismantled — a high-mileage or heavily blocked DPF may have little useful life left. A reputable breaker should be able to tell you the condition of the unit and ideally provide a short warranty. It is also worth having the unit inspected or pressure-tested before fitting, as a partially blocked DPF can cause running problems and potential MOT failure.

DPFs (diesel particulate filters) are fitted to diesel engines, not petrol ones — if your CLE is a petrol model it will have a GPF (gasoline particulate filter) instead, which is a different component. If you're searching for exhaust aftertreatment parts on a petrol CLE, make sure you're asking breakers specifically for the GPF rather than a DPF to avoid wasting time. Confirm the exact part you need against your engine code and registration with the breaker.
